Semi-Rigid Cables

micro-coax Semi-Rigid Coaxial Cables

Semi-Rigid Coaxial Cables

Semi-rigid cable comes as close as possible to the ideal coaxial cable due to its superior electrical performance, exceptional shielding effectiveness, and dimensional stability, making it the first choice of any RF/Microwave engineer. We offer semi-rigid coaxial cable options with a large range of impedances, diameters, materials, and finishes.
